Your house is probably a terrible rental, but if you're really going to do that, at least run *all* the numbers with vacancy/management/maintenance so you understand what you're getting into.
Any freestanding house (ie, not a condo) is going to cost at least a couple hundred bucks a month to maintain (which will come in big chunks at irregular intervals, so I don't want to hear about how you only spend $75 on maintenance this year... wait until you need to do the roof). Managing a rental is a job, so figure out your hourly rate for that and subtract from the return. There will be vacancy when tenants move in/out sometimes, deduct 5-10% for that.
By the time you're done, you're probably losing money, or at best paying yourself minimum wage to manage the place.
Even if you have zero maintenance, management, vacancy, etc costs, $7000 a year on $100-130k of equity is not great.
